Before I order a pre-installed SD Card

Hi All – just trying to get anything working at the mo – I have used the latest SD Card image R15 to create a RPi boot card on several cards – both with Etcher on the Mac and Win32DiskImager on the PC – SD cards previously working with Noobs install of Raspian but each time I boot my RPi 3 and I get a green light for a couple of seconds then nothing – no HDMI signal no sign of RISCOS booting – have tried Pico and that works. Before I order a pre-installed SD card – Am I missing something in the docs? |

It’s possibly failing to detect the monitor resolution, in which case try fixing the resolution in CONFIG.TXT and create a CMDLINE.TXT file with disable_mode_changes in it. Mine did something similar, but went to a solid white screen when I rebuilt it last weekend. Other possibilities are a corrupt FAT partition (use chkdsk or similar) or mismatched RISCOS.IMG / Pi firmware, try updating RISCOS and the Pi firmware files in the FAT partition to the latest build |

The latest firmware won’t work with RC15; there was a breaking change made to the firmware near the end of July, so if you were to update the firmware you’ll also need to update to one of the nightly RISC OS ROMs. I’d start with config.txt and/or cmdline.txt. EDID support in RISC OS is one of the big changes that was made for RC15, but there are a few quirks with the Pi which aren’t fully dealt with. This page has a summary of the settings that you might need to tweak (beyond the ones that you might normally need to tweak for other OS’s, e.g. overscan & config_hdmi_boost) |

Thanks Jon And Jeffrey – that gives me several options to play with – I’ll let you know how I get one :) Thanks, Mark |

I have just found out that RISCOS has been removed from the current list OSs for the RPi3 if running the NOOBS installer – so I’m guessing there is a problem with what I am trying at the moment – I shall perhaps try a different RPi and see if I can get it working – now where did I put that spare Pi Zero :) |

I’m running RISC OS on my Pi 3 … ;-) And ePic will give you a flavour of the available RISC OS applications, along with RISC OS itself. |

Only if what you’re trying is to install via NOOBS ;-) RC15 on the Pi 3 should be no more or less broken than RC15 on any other Pi (until they release a newer model, at least). |

RC15 on the Pi 3 is working perfectly beautifully for me. In 16 million colours on a 3840×2160 screen. I’ve not tried every application under the sun, but everything I’ve tried does. Draw, Paint, StrongEd, Zap, Netsurf, SciCalc, ChangeFSI, and CreateSEC for a start. Getting the screen to do everything I wanted it to do was a bit of a palaver, but it worked at a lower resolution from the start. |

I’ve managed to get a desktop up now – I wrote a card from the latest img file then copied the latest boot files from git and then changed the options in the config.txt hdmi_safe=1 and hdmi_force_hotplug=1 – then it boots to a console error : DataAbort:Abort on data transfer at &FC00B770 (Error Number &80000002) – I then type Desktop and I’m in … except there is no hard disc, floppy etc and I can’t see any way to get anything on to run other than the inbuilt apps. However – running the same card on a Pi Zero Boots to a screen that is looking for a network connection (that it will not find) – so Escape get into the desktop – so I’m getting there with the zero :) |

When you updated the firmware, did you also update the RISCOS rom to the latest nightly build? |

No I didn’t … And that would … at first glance … have flippin done the trick!!! OMG .. meltdown – now all I need to work out is how to transfer my disc images onto the new system. … tomorrow :) Many thanks Mark |

Don’t sweat it. Yesterday, I composed a long involved semi-rant about my keyboard rrrrrrrrepeating badly on the Pi2. I thought this was more or less fixed, certainly seemed to be on my Pi1. But come ttttttthe Pi 2, theeeeeee problem was iiiiiinsanely annoyyyying. Wait… hang on… does THAT say 2015? WTF? How did I end up with a two and a half year old firmware? I’m frankly surprised the CMOS tweak even worked at all with that. So, I pop over to the GitHub link, download the firmware, remember to drop in the disable_mode_changes thingy (as that was more recent than I thought my firmware was) and reboot. And waddaya know? Keyboard repeating issues all gone away. ;-) … tl;dr: Everybody makes mistakes. |
